Abstract:

In recent years, a new type of resin matrix ceramic composite material has already been applied to restore tooth defection as well as to manufacture crowns on implants. It mainly includes two categories: Resin-based ceramic (RBC) and polymer-infiltrated ceramic network (PICN) . This paper provided a review of the mechanical properties, aesthetic characteristics, and clinical applications of resin matrix ceramic composite materials. The results indicated that the mechanical properties of resin matrix ceramic composite materials were between resin composite and ceramics, which were slightly higher than that of resin but significantly lower than that of reinforced glass-ceramics and zirconia. The advantages of such materials included their elastic modulus being close to that of enamel, and better fatigue resistance compared to ceramics. However, further optimization is needed in terms of mechanical strength and fracture toughness. The transparency of resin matrix ceramic composite materials was not as good as that of reinforced glass-ceramics, and their color stability was between resin composite and ceramics. In terms of clinical performance, resin matrix ceramic composite materials have been mainly used for inlays, onlays, and partial crowns currently, exhibiting similar survival rates to ceramics in the short-term clinical follow-ups. PICN may be more suitable for implant-supported full crowns. More evidence is needed to support the long-term clinical performance of these materials.
